My invention relates to building construction and particularly toa novel frame construction for all plaster Walls, that is, Walls in Which there is no Wood or masonry base. The construction heredisclosed provides for extreme rigidity with the minimum of metal and for simplicity in construction and erection. Y Y

A fundamental object is to provide a convenient jamb, plasterterminal and buck, the latter being a bor; ksection thereby insuring maximum resistance to bending for the Weight of metal employed.V Y

T he invention will be more readily under-V stood by reference to the accompanying drawings, in which.

Fig. 1 is a perspective sectional view through a frame constructed in accordance with my invention; andy f y Fig. 2 isa transverse sectional view through a portion of acompleted Wall., Y y.

ln the drawings, I have illustrated the frame as coniposed of a buck of deep Vchannel form comprising aweb 10 and flanges 11, the flanges having Va plurality ofopenings 12 to admit plaster and insure a plaster l-rey'.

Tlie'openings also serve another purpose, that Cf providing for attachment of Vmetal lath 13 by suitable clips or Wires not shown.

At the rear of the buck and Welded to the Wehl@ is a shallow channel member 14e adapted to act as an anchor for the plaster.

At the forward edge the margins of the iauges are laterally bent as at v15 to lie at right angles to the planes of the faces of the yflanges 11. A jamb is Welded to the bent margins 15. The `j amb comprises a flat portion 16, a rearwa'rdlyfbent Vportion 17 and plaster terminal portion. 18 lying in a plane parallel to the flat portion 16 andhaving a relient margin 19 that acts as a plaster key or anchor. Preferably both sides of the jamb members are identical;.however, on one side Iprovide a continuous strip 2O acting as door stop. the strip being Welded to the face 'of the portion 17, or, as shown in dotted lines in Fig. 9., I may construct the stop member of generally Zfshape, the fiat portion 21 lying against the face of the Viamh While the portion 22 acts as the stop. 'The latter construcl metal tion provides sutlicient thickness to allow for adequate cutonts to accommodate hinges.

The Vdescribed partsk are` assembled and ,Welded in the shop and may be shipped and installed Without more than the ordinary skill of an erector. The box section provides for maximum strength and the simplicity of the arrangement'commends itself to builders.

Obviously, the invention is capable of some modification, and Ido notwisli to be limited Vexcept as indicated in the,appendedclaims;

l claim:

l. A combined buck and amb for openings y in all-plaster Walls comprising, incombinafY tion a section of metal bent to 'form a deep and narrow channel, the' margins of the flanges of which are bent to `projectlaterally i at an angle to the piane of the lflanges, and a metal jamb, vthe body portion of which is Welded to the outer faces of. said kbent mar- Welded .to said bent margins, aldoor stop Welded to the amb, and the margins of the jamb being bent to provide plaster terminals. i

`3. A'frame member for all-plaster Walls consisting of a deep channel, and a metal jainb Welded toand closing the open side of the channel thereby providing a complete box section, the edges of the jamb being bent back- Wardly'and outwardly to terminate in flanges that act as plaster terminals.k

4t. A frame member for all-plaster consisting ofadeep channel, a metal jamb Welded to and closing the open side of the channel thereby providing a complete box section, the edges of the j amb being bent baclrvWardly and outwardly to terminate in ianges that act as plaster terminals, and a strip acting as a door stop Welded to the jamb.

vIn ytestimony whereof I have affixed my signature. p f ISAAC? A. BAUM.
